Without the idf ,now, there is a mass pikuach nefesh.
You have not given ANY OTHER WAY to take away this pikuah nefesh.
So, if you cannot find another way to take away the p/n and you do not give a VALID reason not to be drafted in the idf [if they really need you] …. then you are just shofeh damim.
Shofeh damim shel Rabbim !
